Here is my second solargraph - from March 2018 to September 2018.
The pinhole camera was a lager beer can, with a sheet of Ilford Mulitgrade 5x7 paper which fits perfectly without cutting.
Not as nice a picture as my first attempt.
Second solargraph - 2018 10 30

Just to document the deployment of a solargraph pinhole camera on 2018 March 25.
This pinhole camera uses a lager beer can, with a sheet of Ilford Mulitgrade 5x7 paper which fits perfectly without cutting.

My first total solar eclipse was in 1999 - we travelled to France and had a camp-site in the path of totality, so had a good view and little to do on the day except get prepared, and enjoy the experience.
Although there have been a few reasonably accessible total eclipses since then, the 2017 total eclipse which was due to travel across the whole width of the country seemed like too good a chance to miss.
